Description

A hanging device for installing pipelines in ultra-large-scale single crystal silicon production process

Technical Field

The utility model relates to the technical field of construction of monocrystalline silicon process equipment, in particular to an installation hanger for a pipeline of a super-large-scale monocrystalline silicon production process.

Background Art

As one of the indispensable and important components in the production process of monocrystalline silicon, the pipeline involves various aspects of the production process of monocrystalline silicon, such as raw material transportation, air exchange, and heat recovery. In the construction process of the monocrystalline silicon production line, the construction of the pipeline is an important item. However, the installation of the pipeline in the current ultra-large-scale monocrystalline silicon production process is still generally carried out by hoisting.

DETAILED DESCRIPTION

The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

As shown in Figures 1 to 7, an embodiment of the utility model provides an ultra-large-scale monocrystalline silicon production process pipeline installation hanger, including a first bracket 1, a second bracket 2, a first connecting head 3, a second connecting head 4, a first hook 5, a second hook 6 and a support wheel 7. The first bracket 1 and the second bracket 2 are both arc-shaped structures. The first connecting head 3 and the second connecting head 4 are respectively fixedly connected to the top ends of the first bracket 1 and the second bracket 2, and a rod sleeve 8 is fixedly provided on the top of the first connecting head 3, and a plug rod 9 that can be axially inserted into the rod sleeve 8 is provided on the top of the second connecting head 4. The first hook 5 and the second hook 6 are respectively arranged on the first connecting head and the second connecting head 4, and the first hook 5 is clamped with the second hook 6. The support wheel 7 is provided on the upper and lower sides of the first bracket 1 and the second bracket 2, and the first bracket 1 and the second bracket 2 are provided with wheel adjustment components for adjusting the rolling direction of the support wheel 7 parallel to the axial direction and perpendicular to the axial direction.

After applying the scheme of the above embodiment, during the installation of the pipeline, the first bracket 1 and the second bracket 2 can be connected by inserting the rod 9 into the rod sleeve 8. At this time, the support wheels 7 on the first bracket 1 and the second bracket 2 can be supported on the surface of the pipeline, and in this state, the wheel adjustment component is used to make the axial direction of the support wheel 7 parallel to the axial direction of the pipeline to prevent the pipeline from being displaced along its axial direction in the hanger, thereby improving the stability of pipeline hoisting. In addition, after the first bracket 1 is connected to the second bracket 2, the first hook 5 and the second hook 6 are in a clamping state, so that during the process of hoisting the pipeline, the first bracket 1 and the second bracket 2 are stably kept in a clamping fixed state. After the pipeline is hoisted to the specified position, when the support wheel 7 is in a state parallel to the axial direction of the pipeline, the pipeline can be directly rotated in the installation hanger, so that the mounting holes on the flanges of the two butted pipelines can be adjusted to an aligned state in the circumferential direction. Then the wheel adjustment component is used to adjust the support wheel 7 to a state in which the axial direction is perpendicular to the axial direction of the pipeline, and the pipeline can be directly moved in the hanger in the axial direction of the pipeline, so that the pipeline flanges can be butted. Therefore, the hoist not only has the function of stabilizing the hoisting pipeline, but also has the function of adjusting the pipeline state to facilitate the pipeline docking installation.

Specifically, when applying the solution of the above embodiment, after the pipelines are docked, the first bracket 1 and the second bracket 2 can be separated by directly displacing them in opposite directions along the axial direction, and then the first bracket 1 and the second bracket 2 can be removed from the pipeline.

Regarding the connection and separation between the first bracket 1 and the second bracket 2, in an embodiment of the utility model, the first connecting head 3 and the second connecting head 4 are respectively fixedly provided with a first support plate 10 and a second support plate 11, the rod sleeve 8 and the insertion rod 9 are respectively fixedly installed on the top of the first support plate 10 and the second support plate 11, and the rod sleeve 8 and the insertion rod 9 are located directly above the center of the suspended pipe, the rod sleeve 8 is set to a state with both ends open, and the end of the insertion rod 9 away from the second support plate 11 is fixedly provided with a bolt portion 12 extending from the end of the rod sleeve 8 close to the first support plate 10, and the bolt portion 12 is externally threaded with a locking nut 13.

By inserting the insertion rod 9 into the rod sleeve 8, the first bracket 1 and the second bracket 2 can be connected. After the insertion rod 9 is fully inserted into the rod sleeve 8, the bolt part 12 will extend from the rod sleeve 8. At this time, the locking nut 13 is connected to the bolt part 12 to connect and fix the insertion rod 9 and the rod sleeve 8 to prevent the insertion rod 9 from being separated from the rod sleeve 8. When the pipeline is lifted by a crane, the crane hook can be directly put on the rod sleeve 8. It should be noted that in the process of lifting the pipeline, two such lifting devices are used in the length direction of the pipeline.

The hook head of the second hook 6 is in an upward state, the first hook 5 is fixedly arranged on the side of the first connecting head 3, the second hook 6 is installed on the side of the second connecting head 4, and the opposite sides of the first connecting head 3 and the second connecting head 4 are respectively provided with grooves 14 for the hook heads of the second hook 6 and the first hook 5 to pass through.

When connecting the first bracket 1 and the second bracket 2, the first bracket 1 and the second bracket 2 can be placed on the pipe respectively. At this time, the circumferential surface of the pipe is used to make the first bracket 1 and the second bracket 2 staggered in the axial direction of the pipe as a whole, and the first bracket 1 and the second bracket 2 are supported by the pipe. Then, the second bracket 2 is directly displaced in the axial direction so that the insertion rod 9 is inserted into the rod sleeve 8. In this process, the first hook 5 and the second hook 6 pass through the second connector 4 and the groove 14 on the first connector 3 respectively along the axial direction of the pipe.

More specifically, in another embodiment, one end of the second hook 6 away from the first hook 5 is rotatably mounted on the side of the second connector 4 through a rotating shaft, and a torsion spring is arranged between the rotating shaft and the second connector 4. The elastic force of the torsion spring can keep the hook head of the second hook 6 in a state that can be engaged with the first hook 5. In the specific application process, the first bracket 1 and the second bracket 2 are connected, and the insertion rod 9 can be inserted into the rod sleeve 8 first. At this time, the second bracket 2 and the first bracket 1 can swing with the rod sleeve 8 and the insertion rod 9 as the axis. Then, the first bracket 1 and the second bracket 2 can be directly swung relative to each other later, and the hook head of the second hook 6 can pass over the hook head of the first hook 5 by swinging downward, and finally the first hook 5 and the second hook 6 can achieve an engaged state. Therefore, when the second hook 6 is arranged as above, it allows the first bracket 1 and the second bracket 2 to be engaged and fixed by relative rotation, which provides another effective implementation method for the connection of the first bracket 1 and the second bracket 2, and is more convenient for specific operations.

Among them, in one of the application examples of the support wheel 7, the support wheel 7 includes a U-shaped wheel frame 7.1, a wheel body 7.2 rotatably installed between the two ends of the U-shaped wheel frame 7.1, and a wheel axle vertically arranged on the surface of the U-shaped wheel frame 7.1, and the wheel adjustment component includes a rotating rod 15 vertically fixed on the outer end of the wheel axle, and two positioning rods 16 vertically arranged on the inner side of the rotating rod 15. The two positioning rods 16 are symmetrically distributed on the outer side of the wheel axle in the length direction of the rotating rod 15. Positioning grooves 17 for inserting the inner ends of the positioning rods 16 are provided on the surfaces of the first bracket 1 and the second bracket 2, and four positioning grooves 17 are provided, and the four positioning grooves 17 are centrally symmetrically distributed with the wheel axle as the center.

When the positioning rod 16 is inserted into the positioning groove 17, the axial state of the wheel body 7.2 can be maintained. When adjusting the axial direction of the wheel body 7.2, the rotating rod 15 can be directly pulled outward to separate the positioning rod 16 from the positioning groove 17, and then the rotating rod 15 can be directly rotated to adjust the axial direction of the wheel body 7.2, and then the rotating rod 15 can be released to reinsert the positioning rod 16 into the positioning groove 17 at the corresponding position, so that the adjusted support wheel 7 can be fixed.

The axle includes a sleeve 7.3 and a shaft body 7.4. The inner end of the shaft body 7.4 is inserted into the cavity of the sleeve 7.3. The rotating rod 15 is fixedly mounted on the outer end of the shaft body 7.4. A spring 7.5 is provided between the shaft body 7.4 and the sleeve 7.3 to provide elastic force for the positioning rod 16 to be inserted into the positioning groove 17. When the rotating rod 15 is pulled outward to separate the positioning rod 16 from the positioning groove 17, the shaft body 7.4 moves outward in the sleeve 7.3, and the spring 7.5 is stretched. After the rotating rod 15 is released, the elastic force of the spring 7.5 can automatically insert the positioning rod 16 into the aligned positioning groove 17.

A slider 7.6 is provided on the inner side surface of the shaft body 7.4, and a slide groove 7.7 is provided on the inner wall surface of the cavity of the sleeve 7.3 for the slider 7.6 to slide along the axial direction of the sleeve 7.3. The cooperation between the slider 7.6 and the slide groove 7.7 provides a guide for the displacement of the shaft rod in the sleeve 7.3. At the same time, the cooperation between the slider 7.6 and the slide groove 7.7 enables the shaft rod to rotate when the rotating rod 15 is rotated, and the shaft rod uses the slider 7.6 and the slide groove 7.7 to rotate the sleeve 7.3, and the sleeve 7.3 drives the wheel body 7.2 to rotate through the U-shaped wheel frame 7.1, so as to adjust the axial direction of the wheel body 7.2.

A first gear 18 is sleeved on the U-shaped wheel frame 7.1, and second gears 19 are meshed on both sides of the first gear 18. A threaded sleeve 20 is fixedly penetrated through the center of the second gear 19, and a threaded rod 21 is connected to the inner thread of the threaded sleeve 20. An arc-shaped clamping plate 22 is fixedly connected to the inner end of the threaded rod 21, and the threaded rods 21 corresponding to the two sides of the same support wheel 7 on the first bracket 1 and the second bracket 2 are fixedly connected to the same arc-shaped clamping plate 22, and a through hole 23 is opened on the arc-shaped clamping plate 22 for the support wheel 7 to pass through.

During the rotation of the U-shaped wheel frame 7.1, the first gear 18 drives the second gears 19 on both sides to rotate, the second gear 19 drives the threaded sleeve 20 to rotate, and the threaded sleeve 20 drives the threaded rod 21 to move along its axial direction. At this time, the threaded rod 21 drives the arc clamping plate 22 to clamp or loosen the pipe. In this way, the state of the arc clamping plate 22 can be adjusted synchronously during the process of adjusting the axial direction of the wheel body 7.2. The details are as follows:

When the axial direction of the wheel body 7.2 is adjusted to be perpendicular to the axial direction of the pipeline, the arc clamping plate 22 can loosen the pipeline, that is, adjust the position of the pipeline along the axial direction of the pipeline. When the axial direction of the wheel body 7.2 is adjusted to be parallel to the axial direction of the pipeline, the arc clamping plate 22 can clamp the pipeline, and then the state of the arc clamping plate 22 can be automatically adjusted according to the state of the pipeline hoisting or docking.

By providing the through hole 23, the wheel body 7.2 can enter the through hole 23 when the arc clamping plate 22 moves outward to loosen the pipe, thereby enabling the arc clamping plate 22 to cover the first bracket 1 and the second bracket 2 in the axial direction of the pipe, so that it has more clamping surfaces for the pipe, thereby improving the clamping effect.

The bottom ends of the first bracket 1 and the second bracket 2 are both installed with height-adjustable support legs 24. Specifically, in this application example, the support legs 24 include a support rod, a support tube and a support plate. The top ends of the two support rods are respectively fixedly connected to the bottoms of the first bracket 1 and the second bracket 2. The two support tubes are respectively threadedly sleeved on the outside of the two support rods, and the support plate is rotatably installed on the bottom ends of the support tubes. At this time, by rotating the support tube, the length of the support leg 24 can be adjusted to achieve the function of adjusting the height of the pipeline, so as to facilitate the docking of the pipeline.

Among them, in the above-mentioned embodiment of the utility model, the central angle of the first bracket 1 and the second bracket 2 is less than 90°. After the first bracket 1 and the second bracket 2 are connected, there is a gap between the two at the bottom of the pipe, which makes it easier to remove the first bracket 1 and the second bracket 2 from the pipe. At the same time, a certain distance is created between the two supporting legs 24, thereby improving the stability of the supporting legs 24 in supporting the pipe.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
